Game/custom server explanation, please?

I have created a start place in my Game, and within the game has a template place. I believe this is how you start with custom servers.

But how do I continue? How is server-management done? I'm planning on creating a server list, having only certain people making servers (which copies the template place, I believe).

But how do I get all of the servers in the Game? How do I delete servers? I've looked at the wiki page and it doesn't seem to explain it.

If you're not understanding what I'm trying to say, I guess I'm trying to accomplish something similar to what Heist does with creating/deleting its servers for the heists themselves
